DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1 which is a top view of a dinosaur foot print tile ([0045] 10). The method (110) of manufacturing footprint tiles (10) comprises the step of rolling (112) tile base (12) to a predetermined uniform thickness. Preferably, the thickness is between ¼ and 1 inch.
Referring to FIG. 2 which is a cross sectional view along LINE [0046] 2-2 of FIG. 1. The method (11) further consists of the step of imprinting (114) by utilizing a plate or roller with a plurality of convex footprints and exerting pressure upon the rolled tile base (12) forming a plurality of concave footprint impressions (14) into the tile base (12). The plate can be utilized in conjunction with a conveyor belt upon which the tile base (12) is advanced to a predetermined distance and the plate “stamps” the footprint impression into the tile base (12). Alternatively, a roller containing convex footprints can either roll along the top of the tile base (12) or remain in rotationally mounted one position wherein the tile base (12) moves along on a conveyor thereunder.
The method ([0047] 11) further consists of the step of cutting (116) by utilizing a plate or roller with a plurality of blades complementarity positioned to the plurality of concave footprint impressions (14) and exerting pressure upon the rolled tile base (12) forming individual foot print tiles (10). The blades must be contiguous such that individual footprint tiles (10) are formed by cutting. It is necessary to properly position the blades to cut around the footprint impressions (14) positioning them in an approximate central position on the footprint tile (10) face. The blades can cut footprint tiles (10) into different sizes and shapes which are complimentary and can be installed (laid) with small equidistance spaces there between.
The method ([0048] 11) further consists of the step of drying (120) the individual foot print tiles (10). Which is usually accomplished using a kiln, oven or baking in sunlight.
Optionally, the method ([0049] 11) may further consist of the step applying (116A) coating on the individual foot print tiles (10) which functions to protect and preserve the tile base (12) during use. The tile base (12) is selected from a group consisting of clay, clay composites, plastic, plastic composites, fiberglass, epoxy, rubber and rubber composites. Preferably, the tile base (12) is clay or clay composite and the the coating is glaze.
FIGS. 1A, 1B, [0050] 1C, and 1D are top views of a dog foot print tile (10), bird foot print tile (10), monkey foot print tile (10), and racoon foot print tile (10), respectively. Preferably, the concave footprint impressions are animal footprints which are selected from a group consisting of dinosaur footprints, ostrich footprints, monkey footprints, cat footprints, dog footprints, racoon footprints, and bird footprints, and any other animal or homo sapien footprint.
It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of constructions differing from the type described above. [0051]
While the invention has been illustrated and described as embodied in footprint tiles, it is not intended to be limited to the details shown, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention. [0052]
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
